Poople #661 OILS Answer

Poople #661 started at OILS on June 6, 2027. Its selective opening changes letters in the sequence S>Y, O>W, Y>L, W>P, I>O, L>O, L>P, with 3 par-preserving first moves.

Archive value: this is not a copied daily page. Its tables are calculated for OILS, including 4 legal openings and route signature 4-1-4-1-2-3-4.

Choose how much to reveal

The hint describes the move without naming the word. The full route stays closed until you ask for it.

Reveal a direction, not a word

The current row reads O-I-L-S. Change position 4 and keep positions 1, 2, 3 fixed. Look for a consonant-to-consonant change. 3 different first moves preserve the shortest length.

What changes at every step

  1. Step 1OILS -> OILY

    Tile 4 changes S to Y; the move is sideways by letter shape. OILY has 5 legal neighbors, 1 shortest continuation, and 6 moves remaining. Other legal exits from OILS include NILS, AILS, OWLS.

  2. Step 2OILY -> WILY

    Tile 1 changes O to W; the move is sideways by letter shape. WILY has 7 legal neighbors, 1 shortest continuation, and 5 moves remaining. Other legal exits from OILY include LILY, ONLY, OWLY.

  3. Step 3WILY -> WILL

    Tile 4 changes Y to L; the move is sideways by letter shape. WILL has 17 legal neighbors, 1 shortest continuation, and 4 moves remaining. Other legal exits from WILY include WILD, WILT, WILE, LILY.

  4. Step 4WILL -> PILL

    Tile 1 changes W to P; the move is closer by letter shape. PILL has 15 legal neighbors, 1 shortest continuation, and 3 moves remaining. Other legal exits from WILL include BILL, HILL, WALL, FILL.

  5. Step 5PILL -> POLL

    Tile 2 changes I to O; the move is closer by letter shape. POLL has 12 legal neighbors, 1 shortest continuation, and 2 moves remaining. Other legal exits from PILL include PULL, PALL, BILL, HILL.

  6. Step 6POLL -> POOL

    Tile 3 changes L to O; the move is closer by letter shape. POOL has 8 legal neighbors, 1 shortest continuation, and 1 move remaining. Other legal exits from POLL include ROLL, TOLL, PULL, DOLL.

  7. Step 7POOL -> POOP

    Tile 4 changes L to P; the move is closer by letter shape. POOP has 11 legal neighbors, target reached, and 0 moves remaining. Other legal exits from POOL include POOR, POOF, TOOL, COOL.

Opening decision

Which first moves preserve par?

OILS has 4 legal one-letter neighbors. OILY, NILS, AILS keep the route at 7 moves, while sampled detours begin OWLS (+2).

OILS opening fingerprint

OILS groups its legal first moves as tile 1: NILS, AILS; tile 2: OWLS; tile 4: OILY. Two moves from the start, 14 off-route words are reachable; the nearest sampled frontier is AIDS, NIBS, NITS, AILS, AIMS, AIRS, LILY, NILS, NIPS, AWLS, ONLY, OWLY, OWES, OWNS.

OILY is the narrowest displayed bridge

After OILS becomes OILY, only 1 move preserves the shortest remaining distance. At the prior row, alternatives such as NILS, AILS, OWLS show what the route declined.

How these figures were calculated

Poople recomputes adjacency and distance from the accepted 2,398-word graph. "Shortest routes" counts every path that lowers the remaining distance by one at each move; it is not a guess based on page text or player scores.

The displayed answer is one shortest route selected from that graph. Community scores and notes are kept separate because they describe player activity, not the mathematical route.
